Cone Initiation and Development, and Phenology

in Platycladus orient alls Dong Yuan Yin Weilun(Forest Resources College, BFU)Wang Shasheng(Experimental Center of Forest Biology, BFU)  
Vegetative shoot growth in Platycladus orientalis begins in late April and continus until early October .After mid-October vegetative shoots appear to be dorment. The transition of a previously vegetative shoot into a reproductive shoot takes place during long days, though day length decreases from mid-July until early August .Pollen-cone apices are globose, seed-cone apices are cylindrical. Cone development is from mid-August until early October and appears to be dormant after mid-October, Pollination and fertilization occur by the end of March of the following year. Seed cones mature in early October. A branch bearing seed cone is longer than one bearing pollen cone and is crooked at an angle of 90? Seed cones are fewer and are commonly born at the tips of adaxial lateral branches near the base of 1-year old branches.The timing of cone initiation and the sexuality of cones in Platycladus orientalis are compared and discussed in relation to other conifers
